LDAP issues with Cas Server 3.0.5

[Maniesh Sailoz]

I am trying to validate users with LDAP server on CAS 3.0.5 (default ldap adaptor).
I am able to view the CAS login UI but shows following error on login.
*---------------------------------------------
CAS is Unavailable

A general exception occurred while trying to access CAS. Please notify your system administrator.
*---------------------------------------------

The application log doesn't display any errors. Below are the messages from stdout.log. Is there any way to debug what is failing?
